Energy transition and renewable overcapacity are making curtailment optimization a key competitive advantage for energy companies and renewable operators.

Why Curtailment Optimization Matters?

As renewable penetration increases across European power markets, curtailment is becoming a major power market challenge. Grid congestion, negative prices, and demand imbalances are forcing renewable producers to reduce generation more frequently. Companies that optimize curtailment through automation and flexibility will gain a competitive advantage.

Key benefits

Enhanced profitability and operational efficiency

By leveraging automation, analytics, and real-time market signals, companies can optimize renewable generation, reduce curtailment losses, and improve asset utilization. This enables operators and traders to maximize revenues, react faster to market changes, and improve operational efficiency across increasingly complex power markets.

Better operational flexibility across renewable portfolios

Integrated forecasting and optimization capabilities improve flexibility across renewable portfolios, helping operators adapt generation and trading strategies in real time.

Reduced exposure to negative pricing and congestion events

Advanced forecasting and automated strategies help reduce the impact of negative prices, congestion, and curtailment events.

Increased participation in balancing and ancillary services

Integration between renewable assets and market platforms enables greater participation in balancing and ancillary service markets.

Improved profitability through automated optimization strategies

Real-time market data and automated optimization tools help maximize renewable asset profitability and reduce curtailment losses.

How NTT DATA helps

01

Simulation and planning tools

Advanced analytics and forecasting models allow companies to simulate future congestion, renewable generation and market conditions to prepare optimized operational strategies.

• Continuous monitoring and OT threat visibility

02

Automation and algorithmic trading

Production and operational systems (as Syntphony Power Trading) can be connected with market platforms and CTRM/ETRM solutions to maximize profitability through automated market participation.

03

New Flexibility Assets for Renewable Optimization

Battery Energy Storage Systems (BESS), pumped hydro and green hydrogen production help absorb renewable excess and reduce curtailment exposure. Modern digital platforms and market optimization technologies enable the integration of these new flexible assets into existing operational and trading processes.

Establishing governance and cost optimization models

04

Real-time control systems

The integration of additional operational, market, and forecasting systems enables greater visibility, automation, and optimization capabilities across renewable operations. For example, SCADA and Power Plant Controllers (PPC) automatically regulate generation output through setpoints and dynamic operational controls, providing critical real-time data to support more efficient decision-making and optimization strategies.

Develop advanced NLP classification models

Proven impact

Renewable growth is outpacing grid adaptation, forcing operators to balance profitability, stability and flexibility in increasingly volatile power systems.
